Vodafone had earlier slashed effective data rates of its 4G, 3G big internet packs for prepaid customers offering up to 67 per cent more benefits for the same price, tracking a similar move by rivals Bharti Airtel and Idea Cellular.

Customers in Delhi, Mumbai and Kolkata can avail the offer by recharging with Rs 250 and above, and can use the data anytime during the day. However, subscribers in the country's 3G circles can only use the free data in night from 12am till 6am, even as having a 4G phone is mandatory for them to avail the offer.

In addition to data benefits, Vodafone customers will get free subscription to Vodafone Play service, which offers over 100 Live TV channels, over 18,000 movies and TV show titles and a wide range of all genres of music, in partnership with Hungama Play and HOOQ.

The telco said the additional data provided on these packs will make the internet more affordable for customers who use mobile internet in a limited way and encourage first time users to come online. It added that the additional data will also enable existing users of data enjoy their mobile internet experience further by staying online longer and accessing more of their favourite content.
